does this URL work for you?https://embed.windy.com/embed2.html?lat=39.835&lon=-84.112&zoom=5&level=surface&overlay=temp&menu=&message=&marker=&calendar=&pressure=&type=map&location=coordinates&detail=&detailLat=39.835&detailLon=-84.112&metricWind=default&metricTemp=%C2%B0F&radarRange=-1

You are running Windows & Chrome, right? Than just press F12, click Console tab and refresh site. If you do not see any error here, I am affraid we cannot help you. We are not able to reproduce the error at any device :-(

Can confirm that I am unable to get temperature to show Fahrenheit on embedded maps as well. Using the &metricTemp=%C2%B0F option doesn't appear to do anything when viewing the map (both on the Preview as well as the actual embed code). I've tried 4 different internet browsers that all show the same issue.

For what it is worth, I still cannot get any of my devices to show the widget with units in Fahrenheit rather than Celsius. I have tried Google Chrome and Microsoft Edge. I've tried on three windows machines and a Chromebook.

Edit After checking a couple of more times: I did manage to get an error to pop up in the console on the edge browser. I have no idea if it has an significance.
